Understanding Proportional Relationships

This video covers module 1, lesson 3, focusing on identifying proportional and non-proportional relationships in tables. It includes examples like babysitting pay and driving distance to illustrate the concept of constant proportionality. Exercises are provided to practice determining proportionality in various tables. The lesson concludes with a summary and a problem set to reinforce learning.

What is the term used to describe the consistent value that relates two proportional quantities?

• Constant of Proportionality

• Scale Factor

• Variable Ratio

• Unit Rate

In a table showing a proportional relationship, what must remain consistent across all rows?

• The sum of the values

• The constant of proportionality

• The order of values

• The difference between values

How can you verify if a table represents a proportional relationship?

• Check if all ratios simplify to the same value

• Verify if the first value is zero

• Ensure all values are increasing

• Ensure all values are decreasing

If a table has one ratio that differs from the others, what can be concluded?

• The table is incomplete

• The table needs more data

• The table is not proportional

• The table is still proportional

In the context of driving from New Jersey to Florida, what does the constant of proportionality represent?

• The total distance traveled

• Gallons per mile

• The number of stops made

• Miles per gallon

What is the equation form used to represent a proportional relationship?

• Y = C - X

• Y = X / C

• Y = C * X

• Y = X + C

What happens if just one row in a table has a different constant of proportionality?

• The table needs to be recalculated

• Only that row is not proportional

• The entire table is not proportional

• The entire table is still proportional

What is another term for the constant of proportionality?

• Ratio

• Scale Factor

• Coefficient

• Variable

Why is it important to label variables X and Y in a proportional relationship?

• To simplify the equation

• To avoid using numbers

• To make the table look organized

• To ensure clarity in calculations

What should you do if you don't immediately see the constant of proportionality in a table?

• Add all the values

• Divide the values to find the ratio

• Multiply the values by a random number

• Ignore the table
